F5 Vipiron and Weblogic w/JessionID
We've just just installed some new F5 devices into our network to replace older Cisco CSS content switches and are running into issues with an WebLogic Forms instance. We are trying to create session persistence via the JsessionID in the URI, but getting very inconsistent results. There are times that the device is "reload balancing" once the jsessionid is established that is causing our application to error out with a connection error.
Essentially, the app is launched via a servlet going through the VIP, once the jsessionid is established, sometimes we are reload balanced to a different application server. We are able to work until the initial session times out and tries to reconnect and then JRE errors out.
We've been trying a couple of "templates" for IRules to get closer to a functional model, but continue spinning our wheels...
We've been tracing via TCPdumps and its always erroring out when the initial session is re-balanced when the jsessionid is established.
IP based session persistence is not an option due to the infrastructure that we are dealing with and simple cookie based was not reliable due to other parts of our app.
Any thought or ideas on IRules that would take a default load balanced persistence and tie it to a jsessionid that is created could be a great help.
